HUB-NUT.

Specification of Letters Patent.

Patented July 26, 1910.

Application filed October 13, 1909. Serial No. 522,386.

To all whom it may concern:

Be it known that I, WILLIAM A. STEWART, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inHub-Nuts, of which the following is a specification.

My invention relates to an improved hubnut, the object of the inventionbeing to provide an improved nut of this character, which is adapted toscrew onto the end of the axle spindle, to secure the wheel hub on thespindle, and which is capable of varying adjustments to take up wear andprevent rattling.

A further object is to provide an improved device of this characterwhich is of extremely inexpensive construction, yet strong and durablein use.

With these and other objects in view, the invention consists in certainnovel features of construction and combinations and arrangements ofparts as will be more fully hereinafter described and pointed out in theclaim.

In the accompanying drawings, Figure 1, is a fragmentary view inlongitudinal section, illustrating the application of my improvements.Fig. 2, is an end view. Fig. 3, is a detail view of the ring 9, and Fig.4, is a detail view of the washer 10.

1, represents an ordinary axle spindle, and 2 an ordinary boxingthereon, around which latter an ordinary hub 3 is mounted, and providedat its end with a metal tubular extension t.

5 represents my improved nut, which is of general cylindrical form,having a central enlargement or extension 6 which is made angular on itsexterior to receive an ordinary wrench to adjust the nut. Thisenlargement 6 is made with an internally screw threaded bore 7 to engagethe restricted screw threaded end 8 of spindle 1.

In the nut 5, a metal ring 9 is located and a washer 10, preferably ofleather or other suitable material, is interposed between the ring 9 andthe end of boxing 2. This washer 10 has an opening which is large enoughto admit spindle 1, so that it does not bear against the end of thespindle, but only against the boxing. The circular body portion 11 ofthe nut receives the end of boxing 2. The nut 5 around the enlargement 6is provided with a series of screw threaded openings 12, in which screws13 are mounted. These screws, at their outer ends, preferably lieapproximately flush with the surface of the nut, and at their inner endsbear against ring 9, so that when said screws are adjusted, ring 9 andwasher 10 will be moved.

When the nut is screwed on to the threaded end of the spindle 1, thewasher 10 will bear against the end of the boxing, and as the boxing orthe washer wears, the washer may be adjusted by means of the screws 13to compensate for wear, and a uniform tight bearing is assured.

It will be noted that my improved nut may be utilized with any ordinaryform of axle spindle and hub, and it is designed to take the place ofordinary nuts now used, and will to a great extent, obviate rattling,which cannot be prevented with the ordinary nuts. Various slight changesmight be made in the general form and arrangement of parts described,without departing from my in vention, and hence I do not restrict myselfto the precise details set forth, but consider myself at liberty to makesuch changes and alterations as fairly fall within the spirit and scopeof the appended claim.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is In combination with an axle spindle having arestricted screw-threaded end, a boxing on said spindle, and a hub onsaid boxing, of a nut, comprising a body portion of general cylindricalform of an internal diameter greater than the external diameter of theboxing, a central enlargement on said nut having an angular exterior andan internally screw-threaded bore to engage the threads on the spindleend, a metal ring in said nut fitting the recess in the latter andhaving a central opening but slightly larger than the screw-threadedportion of the spin dle, a Washer in the recess in said nut between thering and the end of the boxing,

and bearing against the boxing only said nut having an annular series of"screwthreaded openings, and screws in said open-, ings bearing againstsaid ring, substantially as described.

In testirnony whereof I have signed my name to th s speclficatlon in thepresence of 10 two subscribing Witnesses.

WILLIAM A. STEWART.
